The SKU is unique for each product and used for internal tracking purpose only so that if the same product is sold by different sellers, the SKU can be different too. Furthermore, SKU is usually used to refer products in the inventory list, order form, invoice, etc.

  • More Professional

Having SKU becomes the standard in selling products. It is even required for multi-channel selling. When you want to sell your products in other stores, you may need to input the SKUs too. For instance, if you want to sell on Amazon, you’re required to assign SKUs for your products. It is because SKU is used to access all product information quickly.

How to Create SKU

There is no exact rule in creating SKUs. You can combine letters and numbers based on the product itself. You can assign the important characteristics of the product such as brand, product category, color, or even size. The order of the code should follow the natural hierarchy of the product. But the format of SKU is still up to you.

For example, you want to create SKU for shoes from Dahz 2017 series. You can make it as DHSH178WH. DH is the code for the brand, SH is the type of product, 17 is the code for the series of product, 8 for the size, and WH for the color. You can generate the information from the SKU that the product is Dahz Shoes from the 2017 series, the size is 8 and the color is white.

In WooCommerce, you can input SKU directly when you add a product within the Product Data. There you can input the SKU, manage the number of stock quantity and stock status. In Upscale, you can feature products to display simply by inputting the SKUs of the products. You can feature the new arrivals or highlight the discounted products easily.

Tips on Creating SKU

  • Use consistent format.
  • Keep it short and simple to be easily understood; better keep it as 8-12 characters.
  • Don’t use special characters; if you must, only use dashes (-) or underscores (_).
  • Avoid using letter O, I, or L that can be confused with numbers.
  • Don’t use zero at the beginning, use letters instead.


SKU certainly helps you to ensure the accuracy and efficiency in managing orders and product inventory. When your eCommerce becomes bigger with much more products added, surely you don’t have to start from scratch to use SKU for managing inventory.
